Sinoatrial node dysfunction and deafnessOMIM Phenotype
Preferred Label : Sinoatrial node dysfunction and deafness;
Symbol : SANDD;
CISMeF acronym : SANDD;
Type : Phenotype, molecular basis known;
Description : Patients with sinoatrial node dysfunction and deafness have congenital severe to profound
deafness without vestibular dysfunction, associated with episodic syncope due to intermittent
pronounced bradycardia (Baig et al., 2011). See Jervell and Lange-Nielsen syndrome
(220400) for discussion of another deafness syndrome with impaired cardiac conduction.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the alpha-1D subunit of the L-type voltage-dependent calcium
channel gene (CACNA1D, 114206.0001);
